EYE LE T-STAY-JOINING MA CHINE Specification of Letters Patent.

Patented March 2, 1909.

Application filed February 3, 1908. Serial No. 414,093.

To all whom it may concern:

Be it known that I, FREDERICK L. ANDER- SON, a citizen of the United States, residing at Haverhill, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Eyelet-Stay-Joining Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to mechanism for joining or splicing the stays used to reinforce the uppers of shoes along the eyelets thereof. These stays are made in two pieces, and are joined at their abutting ends by a splicing piece or tape or by lapping the ends of the stay on each other.

The principal object of the invention is to provide a mechanism whereby the stays to be joined will be under pressure during the greater portion of the time, consumed by the pressing mechanism, and whereby the maximum pressure may be obtained. v

Another object of the invention is to allow two stay sections of leather or other substance to be joined together with adhesive tape to receive nearly uniform pressure during the joining operation.

Another object is to provide a simple and efficient machine of this character provided with means for automatically feeding the tape to the stays, and with automatic means for discharging the spliced stays when finished.

In the accompanying drawings, Figure 1. is a side elevation of this improved machine with the table removed; Fig. 2 is a similar view taken from the opposite side oi the machine Fig. 3 is a side elevation of a portion of the bed plate and pressing member or block, the latter being in elevated or inoperative position; Fig. 4 is a similar view showing the presser member in its lowered or operative position; Fig. 5 is a plan view of the member shown in Fig. 3; Fig. 6 is a top plan view showing the arrangement of the stay-discharging and tape-feeding devices Fig. 7 is a front elevation of the tape feeder; Fig. 8 is a top plan view thereof; Fig. 9 1s a rear elevatlon showing the stay-counting mechanism; Fig. 10 1s a top plan view of said mechanism;

Fig. 11 is an end view of a portion of the bed plate, presser member and plunger; and Fig.

12 is a side elevation of the lower portion ol the plunger.

In the embodiment illustrated, a bed plate, 1, is shown sustained in position by a supporting structure of any desired construction, and a pressing member, 2, is yieldingly supported above and adapted for contact with the bed plate, 1. This member, 2, comprises two vertically spaced horizontally disposed plates or members, 3, 3, the upper one, 3, of which is formed by two separate sections, 4, 4. Said plates, 3 and 3, are preferably connected by screws, as 5, which pass through the lower plate, 3, and into the upper plate, 3, the heads of said screws, 5, being arranged to slide in corresponding sockets, 6, formed in the lower plate, 3.

Vertically disposed coiled springs, 7, are fixed to the bed plate, 1, passed through cor responding openings in the lower plate, 3, of the presser member and have their upper ends fitted in sockets formed in the under or lower face of the top plate, 3 of said member, 2. By this arrangement it will be evident that the presser member, 2, is yioldingly supported above the bed plate, but may be moved in contact therewith when pressure is applied thereto. Yielding means, preferably in the form of a rubber cushion or plate 7 is arranged between the plates, 3, 3, to provide additional yielding resistance when the bottom plate, 3, has reached the bed plate, 1, of the machine.

Vertically disposed guide members, 8, preferably in the form of screws passed through openings in the bed plate 1, and screw into the lower plate, 3, of the presser member, said screws serving as a guide for the presser member when the latter is actuated.

A table, 9, is fixed at its inner end by a fastoning screw, 10, or other equivalent means, to the top of the bed plate, 1, at each end of the presser block, 2, and the stays to be joined are piled upon this table. A plunger, 11, is shown provided at its rear face and lower end with a suitable die, 12, which is removably retained in position by a screw, 13, or other equivalent means and is adapted to cut oil a section of the tape for joining the eyelet stays together. This plunger may be actuated by any suitable means preferably by an eccentric, 90, on a shaft, 100, driven by any suitable means.

The bed plate, 1, is provided adjacent the rear side of the presser block with an upright dle, 14, havinga sharpened upper edge, and in the application of the invention, the tape is intermittently fed by a suitable feeding mechanism, hereinafter described, over said die and onto the face of the presser member under the plunger.

The plunger, 11, is provided at its rear face with a suitable guide way, 15, in which is arranged to slide vertically a tape-holding member, 16, having an outwardly extending serrated lower end, 17 and a pin orextension, 18, on its rear face adapted to operate in a slot, 19, formed in the rear face of the guide member. Said guide member is provided at one edge with a horizontally disposed arm or extension, 20, to which is fixed a spring, 21, the upper end of said spring being arranged to engage a pin or projection, 22, extending outwardly from the rear face of the guide member, and the lower or opposite end is arranged to engage the pin or extension, 18, of the slide, 16. The tendency of this spring, 21, is to normally press downward on the pin, 18, for a purpose to be described. The lower end, 17, of the slide, 16, is preferably in the form of a rearwardly and downwardly inclined finger adapted to engage the correspondingly inclined inner face of the free end of a flat spring, 23, which is secured at its other end to the table, 9, to hold the tape during the backward movement of the tapefeeding finger to be described. The finger, 17 of the slide, 16, normally projects below the lower face of the plunger, 11, so that the tape will be gripped by the finger or extension, 17, before the plunger reaches the pressing block. As soon as the finger, 17 grips the tape, the slide moves upward in the guide member, 15, of the plunger, 11, to prevent retarding of the descent of the plunger.

A tape-carrying reel, 24, is mounted on a laterally extending arm, 25, at the rear of the machine. The tape, 26, is wound on this reel, 24, and passes over a dampening roller, 27, rotatably mounted in a water tanlr, 26, carried by the machine bed.

The tape-feeding device consists of a bracket, 29, fixed on a plate on the bed plate 1 of the machine, and has its ends upturned and apertured to receive rods, as 30. A block, 31, is slidably mounted on these rods, 30, and is connected with one end of a camoperated lever, 32, fulcrumed at 33 to the machine head or stand, and this lever is provided with a roller, 34, at its free end. Coiled springs, as 35, are arranged on the rods, 30, between the front end of the bloclr 31, and the front bracket arm, and serve to normally hold and to return the bloclr into normal position. A member, 36, is secured to one side of and adapted to move with the block, 31. This member, 36, is provided with a laterally extending arm, 37, at its front end, for a purpose to be described. A

pawl, 38, is fixedly mounted on a laterally extending screw, 39, carried by the member, 36, and is provided at its free end with a detachable serrated plate, 40, preferably made of steel and adjustably secured to the pawl by screws, and this plate is designed to grip the tape and feed it forward as hereinafter described. A spring, 12, bears on the pawl, 38, when the slide, 31, is moved forward and binds the tape tightly between the serrated edge of the pawl plate, 40, and the upper face of the arm, 37.

When the sliding block, 31, moves backward under the action of the springs, as 35, the pawl, 38, swings outward and the tape is held between the fingers, 17 of the sliding plunger-carried member, 16, and the serrated end of the spring, 23.

The blOCl'I, 31, carries an adjustable stop, 31 to regulate the length of the tape to be fed forward. As shown, this stop comprises an L-shaped plate having longitudinally arranged slots, as 31, through which binding screws, as 31, pass for securing the stop to the block 31. The short arm of the plate, 31 is arranged to engage the upturned end of the bracket, 29, when the block 31 is returned by the springs after feeding the tape forward. W hen it is desired to feed a long piece of tape, the screws, as 31 are loosened and the plate moved forward and fastened by tightening up the screws 31; and to shorten the tape fed, the reverse operation takes place, the plate or stop 31 being moved backwards and secured in the desired position by the screws 31.

The lever, 32, is actuated to move the sliding block, 31, of the tape feeding device forward by means of a cam, 91, on the shaft, 100, and this cam is so constructed as to operate the lever, 32, to move the tape forward after a section has been glued to the stays and cut, and the completed stays discharged from the presser block, 2.

A suitable mechanism is arranged to discharge the stays from the face of the presser block into a suitable tray or receptacle, 55, arranged in front of said pressing member, 2, just after the plunger has begun its ascent. This discharge mechanism preferably comprises two arms or members, 44, 15, project ing laterally from the arm, 46, of an L- shaped member,47, and arranged to operate on opposite sides of the plunger, 11, and over the face of the pressing member, 2. A sliding block or member, 48, is connected with the other arm of the member, 17, and slides on rods, as 48, supported in a bracket, 19, similar to the bracket 29, of the tape feeding device, with springs, as 50, arranged thereon to return the block after actuation. A link, 51, is connected at one end with the sliding block, 48, and at its free end with a lever, 52, fulcrumed near its upper end, at 53, to the supporting structure and carrying a roller,

54, .at its upper end. The horizontally disposed shaft, 100 is rotatably sustained by the frame or supporting structure adjacent the upper or fulcruined ends of the levers, 32 and 52, and this shaft is provided with cams, 91 and 92, which are so positioned thereon as to engage the rollers on the lovers, 32 and 52, and impart an oscillatory movement to the lower ends of the levers, 32 and 52, when the shaft is rotated.

A particular feature of the invention resides in forming the top or upper plate of the ressing block in two sections and support ing it on auxiliary cusl'rioning means to provide for the movement thereof relatively to each other to permit the same pressure to be applied on the two stay sections that are to be joined When such sections are of uneven thicknesses. As the tendency of the springs, 7, is to maintain the pressing block in an elevated .position, it will also be perceived that pressure will be applied to the adhesive tape and stay sections during the descent of the ressing member as well as after it has reaciied the bed plate.

It will also be noted that as soon as the pressure has been released from the pressing member it will be returned to its normal or initial position by. the springs, 7, ready for the next operation.

In practice, the stay sections are arranged over the face of the pressing member. The feeding mechanism is so timed as to feed the tape forwardly over the stay sections; the plunger then descends, the finger, 17, of the slide, 16, grips the tape and retains it in position before the plunger has reached the pressing block. As the die, 12, carried by the plunger, engages the front face of the die, 14, of the bed'plate, a section of the tape is severed from the roll. This severed portion of the tape is then pressed against the stay sections by the plunger, 11. Because of the construction of the pressing block, pressure is not only applied to the tape after said member has contacted with the bed plate, but during the entire tim consumed by the downward movement of the pressing member. The discharging mechanism is so timed that after the pressing member has returnedto its normal or initial position and the plunger slightly elevated above the same. the joined stay sections will be disclu'rrgod into the tray or receptacle, at the front of the machine.

A counting device for the spliced stays is also mounted on the machine and as illus trated comprises an L-shaped bracket, 56,

secured in any suit-able manner to the ma chine, preferably by screws, 57, passing through one arm of said bracket. Fulcrumed on the other arm is a lever, 58, having an arm, 59, projecting upwardly from' one end in position to be engaged by the roller 59, on the cam, 92, on the operating shaft, 160. This roller 59 is arranged to actuate the arm 59 simultaneously with the actuation of the discharge mechanism by the cam 92. A pawl, 61, is pivoted to the other end of said lever, 58, with a spring, 62, hearing there-against and holding it in engagement with a toothed disk, or dial, 65, rotatably mounted on said bracket.

A spring, 63, bears against the .lower face of the lever, 58, and holds it in operative position. An adjustable stop, 64, is arranged below and bears on said lever, 58. The dial, 65, has ratchet teeth around its periphery and numbers corresponding to said teeth arranged on its front face. This dial is also provided with a plurality of holes, as 66, into which a screw stud, 67, is adapted to be placed so that when the pointer, 68, at the front of the dial, registers the desired number, say, for instance, fifty, a bell will be rung through means new to be described.

A striker or clapper, 70, is pivoted to the bracket, 56, and has an arm or tooth, 71, projecting over the rear face of the dial in position to be engaged by the screw stud, 67, which causes the weighted end of said clapper to strike the bell, 69, and indicate that a certain number of stays have been spliced. The bell, 69, is arranged adjacent the dial, 65, preferably on a plate, 72, depending from the bracket, 56.

it will thus be seen that simultaneously with the actuation of the lever 52 to discharge the completed sta v,the roller 59 on cam 92 moves the arm 59 of lever 58 and the pawl 61 is caused to move the dial 65 one tooth which movement of the dial is indicated on the face thereof by the pointer 68.
